i was IMMEDIATELY turned off by Robin spewing out the F word. Why does all the DC stuff have to be so dark (with the exception of Flash and Shazam. I know, I know. Stop looking at me like that, Perry!)

I will say this about Robin throwing that out there like that ... it damn sure got my attention. And while I completely, 100%, without pause or thought, understand why some fans are turned off/away by that two second shocking phrase, I had the complete opposite reaction.
I had no interest in the show Titans until I saw that "trailer" and heard those two eye opening words.
"Fuck Batman!"
Whaaaaat? Now hold on a minute, I was not expecting that at all. Maybe this will be a different kind of show

The way Geoff Johns described his reasoning for having Robin say that was that Dick had just left ole Batsy. I guess he means that Robin is a modern, young man who finally got fed up with the old man and his shit and has bounced from the crib with deuces flying in the air (am I doing that right?

)
I get it. I was almost exactly that way when I left my dads house. Sometimes overbearing can be overbearing

But again, I get most fans reactions. I do. Who wants to see their heros in that light? They are supposed to be "super" and always (or as much as possible) on the moral high-ground. But think back to when Robin left Batman. Is that phrase really something Robin, in this day in age, wouldn't have said? Maybe, sure, but then again maybe not. And remember, this is Titans without the Teen.

When it comes to some television, movie or book themes, I don't need vulgarity to make them seem realistic or more true to how life is or can be, but when I am watching shows that feature drugs, war, politics or the fantastic feats of "superheroism" and the like, it is nice to have a "fuck you!" in there from time to time to match the high action or tension that is being displayed. There is nothing like that phrase to show you, the viewer/reader, that we are down to business.
But again, I also understand the point that these characters we love so much are loved because they take some of us AWAY from the realism of true life. The whole idea is to escape the real world's obscenities and drown in a pool of easy to digest good versus bad. I get ya.
I just know I was not going to watch Titans and now I am at least going to try it. All because Robin said something that I think fits in a more realistic and less teen melodrama (Arrow) type of way. Yes, I also know the term "realistic" and all its forms is a bad word for some comic readers but while I enjoy the older comics for the way they were, I for one still enjoy the more modern way of writing because it is just that, more real. Well, as real as reading/watching something about people flying around with capes draped over their shoulders. Yep. I am certainly gonna check out Titans now. I think most fans will also give it a look if they are on DC Ultimate ... or whatever it is called. Or at least I hope so.

(On a side note, I also hope I have more info on the comics side of that DC Ultimate before I have to pay for the service to see Titans. I want to do yearly to get the best deal, but I don't want to pay for a year if their comic selection isn't up to par with what I am hoping.)
